.TACKJING ATTACHMENT FOB MOTOR VEHICLES.

Application illed February 12, 1923.' Serial No. 818,491.

Be it known thatl, JOSEPH H. Ieo, a citizen of the United States,residin at Chicago Hei hts, in the county of ook and State of I linois,have invented new and useful Improvements in J acking Attachments forMotor Vehicles, of which the following is a specification.

IThis invention relates to jackin attachments for motor vehicles oftheind described and claimed in my prior Patent No. 1,375,515, grantedApril 19, 1921.

The object of the resent invention is to rovide means where y thecoupling memr of the device. may be carried by the frame of thecar abovethe axle and be swun into and out of engagement with the axle t rough aslidably mounted rod accessible from the exterior of the car body andthus be readily actuated when desired to connect the axle and frametogether for jacking the wheel oli the ground by the jack placed underthe vertical guard of the umper.

The invention consists further in the matters hereinafter described andmore particu larly set forth in the appended claims.

1n the accompanying drawings- Fig. 1 shows the coupling member carriedby the frame of a vehicle at the rear axle and the rod or swinging thesame into and out of operative engagement with said axle, in accorda cewith my invention;

F1 2 is a view of the same parts with the coup in member-swung under theaxle and wheel lifted from the roadway by a jack laced under thevertical guard of the umper; v

Fig. 3 is an enlarged vertical sectional view taken on line 3-3of Fig.2;

Fig. 4 is an enlarged vertical sectional view taken on line 4 4 of Fig.1; v

Figs. 5 and 6 are detailsectional views taken on lines 5-5 and 6-6,respectively, of Fig. 2;

Fig.y 7 is a perspective view of the operating rod;

Fig. 8 is "a vertical sectional view taken on .line 8-8 of Fig. 1, toshow a detail of construction; and

Fig. 9 is a top plan view of the bracket and its attaching means.

1n the drawin s, 1 indicates a side member of the main rame or chassisof an auto- 3 the spring connecting the rear axle with the frame 1, asusual 1n structures of this kind. The axle is provided at each end wltha wheel 4, and the latter of course is outside the frame.

The frame member 1, as shown in Figs. 3 to 5, is channel shape with thechannel opening inward..v Applied over the lower web 5 of the member 1ata point above the axle 2 is -a metal block 6. This, as shownl in saidfigures, is substantially U-shape in cross-section to engage over saidweb 5 from the inside. The block 6 is held in place by a separable plate7 clamped against the outsideof the rame member 1 by a number of' bolts8, as shown.

The block 6 carries a horizontally varranged short rock shaft 9. Saidshaft extends inward from the block inside of the frame member 1, andisthere connected with a coupling member 10. Said member 10' has alength to extend between the frame 1 and axle 2 and has its lower endhook shaped to extend under the axle 2 in order to connect the latterwith the frame 1 in the same manner as described in my prior patvidedbetween its ends with a shallow notch` l or recess 17 to coo erate with.a spring ressed plunger 18 slidably mounted in the lock 13 above therod. When the plunger 18 engages the notch 17, the rod 12 is held in theposition shown in Fig. 1 with the coupling member 10 raised up inside ofthe frame 1 and com letely out of engagement with the axle 2. his is theposition of the parts when not in use.

To release the rod 12 and permit the member 10 to swing by gravity underthe axle 2 and couple the latter with the frame 1, 1 provide the plunger18 with a vertical stem 19 extending above the up r end of the block 13and there provide with a grasping portion or cap 20. The upper end ofthe block 13 is partly cut away to provide an upstanding lug 21, and thecap 20 has its lower end eut awayin a' complementary manner to provide a-dependlng lu 22, which lits against the lu 21 to hol the plungeragainstrotation w en enga ed with the rod 12. To release the plunger romthe rod and permit the latter to be moved, the cap 2O is raised andturned to carry its lug 22 across the one 21, as shown 1n Fig. 6.

In the particular installation shown 1n v the drawings, the block 13 ispivotally carried by the bracket 14. This 1s clamped in a'manner to behereinafter described to the side frame 1 and extends beyond the rearend of the same, as shown in Figs. 1 and 2. The'bumper across the rearend of the car comprises a horizontally arranged bumper bar 23, whichhas a length. to extend from one side of the car to the other, as usualin bumper equipment. Extending across this 2i) bar adjacent each end isa vertical guard member 24. This follows the general arrangement lshownin my said priorpatent and has vertical front and rear sectionsconnected top and bottom by loops, as shown.

vThe rear section 25 is secured to the bracket 14 and a spring 26%* isbetween the sections and bears against the inside of the bar 23 to holdthe latter against the inside of the front section, there being a bolt26 extending l 30 between the parts and through the spring The guard24'has a length to extend downward a suliicient distance to have 'alifting jack 27 reach it, as shown in dotted lines in Fig. 1 and fulllines in Fig. 2. The jack is usedl to lift the wheel 4 from the roadway,and before operating the jack for that purposeY the plunger 18 isreleased from the rod 12 and the coupling member 10 al- 40 lowed to dropby gravity under the axle 2 so as to connect the latter with the sideframe 1 and thus permit the jack 27 to raise the wheel 4 ott' the groundwhen actuated. When not in use, the rod'12 is drawn outward, as shown inFig. 1, to hold the mem# vber l''raised, the plunger 18 holding theparts in that position.

By reason of the rod 12 of my invention, .it is possible to carry themember. 10 asa l. permanent part of the car equipment and readilyreach-it from a point exterior of the ,car body for swingling it intoand out of engagement with te axle 2. This. avoids the necessity ofreaching under the car to apply the member 10 in place and swing it intoand out ofengagement with the axle as heretofore. Thus, the user ofthecar is not required to soil his hands or clothes in using the member'10,inasmuch 'as the rod 00 12 is easily accessiblefrom a point exterior ofthe car body and the rest of the mechanism associated therewith.- Thevertical guard 24 of the bumper being also clear of theA car mechanismmay have the jack 27 5 placed beneath itoutside of the car and berequired to ut the operated without being l ft th 1 E e to i le w ee ojack under the rear ax the roadway as heretofore. The mechanism Adescribed makes convenient and easy the use f the jacking attachment.

It is to be understood that substantially the same constructioncouldbeused at the y14 is attached to the `frame the outside, as shown in Fig.9. Over the topv web 5x of the frame..member 1 are applied twosubstantially U-shaped blocks 28, 28a. These are of course applied oversaid web from the inside and extend to the vertical web 5b of said framemember. One of these front end of the car for the front axle., with" Thel blocks 28 is shown in Fig. 5 and the other 28a in Fig. 8. These blocksare clamped in place by bolts 29, 29, which extend inward through theblocks at their inner ends and out- -ward through the bracket 14 at theouter ends. The bolts are between the blocks and `the web 5l and lie ontop of the latter, as

shown in Figs. 5 and 8.

Below the innermost top block 28a is a.

similar block 30. This is applied over the bottom web 5 and is clampedin place by bolts 31, 31 in the same manner as the other blocks, asshown in Fig. 5. Forward of this block 30 is a lug 32. This is integralwith the bracket 14 'and extends under the lower web 5 and engagesupward against the same.

By reason of said lug, the upward lift on the bracket 14 by the jack 27is transmitted Ito the frame member 1 and relieves the bolts 29 and 31of excess strain. l

While I have shown and described herein in detail a. device of myinvention, it,l is of course understood that the same may be variouslychanged and modified without devention. Y
